` Letters Pa'tent No. 96,055, dated Octobe'r 19, 1869.

The Schedule referred to in these Lettera Patent and making par: o! thesame.

To all whom 'it may concern Be it known that I, CHARLES J TRIPP, ofWallingford, in the county of New Haven, and State of Conneeticut,baveinvented a new Improvement in Flour- Sitters; and I do hereby declarethe following, when taken in connection with the accompanying drawings,and the letters of reference marked thereon, to be a full, clear, andexact description ofthe same, and which said drawings constitute part ofthis specification, and represent, in-

Figure 1, a perspective view, and in Figure 2, a vertical centralsection.

This invention relates to an improvement in device for sifting flour,

In sifters, asv heretofore constructed, after the req- `uisite quantityof flour has been siftcd, the machine itself must he removed, andgenerally the unsifted flour emptied out.

The object of my invention is to construct a fioul'- sifter which may befilled with flour, and as small a portion as desired be sifted, and thebalance remain covered in the sitter, and combining with the sifter areceptacle for the sif'ted our, by means of which it may be removed fromthe machine without in any way .interfering with the unsifted fioul'.

To enable others to construct and use my improvement, I will proceed todescribe the same, as illust-rated in the. accompanying drawings.

.A is the case, constructed of wood or other suitable material, andofasize corresponding to the general use for which the sifter isdesigned.- It is provided with a cover, B, to close the top, and withinthe case is arranged, on suitable slides, a bo'x, C, its bottom, D,being formed ofa net-work of wire, or perforated, as seen in iig. 2, themeshes or perforations being of the proper size for sifting the ourwhich is to be placed wit-hin the box C. Though the side ofthe box acrank-shaft, E, extends, to which a connecting-rod or pitman, F, isattached, connecting the crankiof the shaft with the box, as seen inlig. 2, so that by turning the crank H upon the outside, areciprocatingr movement will be -given to the box C, causing it to passto and fro longitudinally in the case, which motion agitates the our sovas to pass through the meshes in the bottom Beneath the box (l, Iarrange a drawer, I, which, during the operation of sifting, is placedentirely under the box until the requisite quantity of sifted flour haspassed thereinto; then the drawer may be taken out and the flourremoved, and the drawer replaced for further sifting when required.

I do not wish to he understood vas broadly claiming the arrangement of areciprocating sieve within a box,
